[0035] This utility model provides a tooling for detecting empty tubes in a glue dispensing machine, a glue dispensing device, and a conveying device, which solves the technical problems of low efficiency and easy wear in the detection of empty tubes in the prior art, so as to achieve efficient non-contact detection of empty tubes.

[0036] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0037] Please see Figures 1 to 4 The first aspect of this utility model provides a tooling for detecting empty tubes in a glue dispensing machine, comprising:

[0038] Positioning mold 1, which has multiple positioning through holes 10 for storing blood collection tubes 3;

[0039] A laser sensor is aligned with the positioning mold 1 and is used to emit a laser into the positioning through hole 10.

[0040] Reflector 2 is located on the side of the positioning through hole 10 away from the laser sensor. Reflector 2 is connected to the positioning mold 1 and covers all the positioning through holes 10. Reflector 2 is configured to receive the laser from the positioning through hole 10 and reflect the laser back to the positioning through hole 10.

[0041] The laser sensor can be fixedly aligned with the positioning mold 1 by a fixing bracket, so that the laser sensor and the reflector 2 are arranged opposite each other on both sides of the positioning through hole 10. There are various methods for fixing the laser sensor, and those skilled in the art can choose from them.

[0042] In the application scenario of this embodiment, a corresponding number of blood collection tubes 3 are placed in different positioning through holes 10. Then, the laser sensor emits a laser into the positioning through hole 10, and the laser will enter the blood collection tube 3 in the positioning through hole 10. If there is blood in the blood collection tube 3, the laser will have difficulty passing through the blood to reach the reflector 2 and will be reflected from the reflector 2. If the blood collection tube 3 is empty, the laser will pass through the empty tube and the positioning through hole 10 to reach the reflector 2, and the reflector 2 will reflect the laser back. That is, by observing whether the laser returns, it is determined whether the blood collection tube 3 is empty.

[0043] It should be noted that, since the blood collected in blood collection tube 3 is relatively thick, a large blood layer will significantly attenuate the intensity of the laser, reducing the laser's ability to penetrate into the target tissue. In order to reduce the impact of errors, the laser can be a laser with weak or no ability to penetrate blood, or a laser band that will not affect the blood.

[0044] The advantages of this embodiment are as follows: First, it has high detection efficiency. Through the cooperation of the laser sensor, the positioning through hole 10 and the reflector 2, the empty tube laser return can be realized. By judging whether the laser returns, it can be identified whether the blood collection tube 3 in the mold is in an empty tube state. There is no need for repeated visual inspection as in the traditional method, so the detection efficiency is high. Second, it has low wear. The laser can realize non-contact detection of the empty tube state. There is no need to mechanically probe the blood collection tube 3 with a probe as in the traditional method, which would cause wear or demanding positioning requirements for the blood collection tube 3.

[0045] In one specific embodiment, such as Figure 1 As shown, a feasible arrangement of the laser sensor, positioning mold, and reflector is further provided. Multiple positioning through holes 10 are arranged along the height direction of the positioning mold 1. The laser sensor is arranged above the positioning mold 1, and the reflector 2 is arranged at the bottom of the positioning mold 1. In specific implementation, this arrangement can be applied to general production and conveying scenarios and has higher practicality.

[0046] In one specific embodiment, such as Figure 3 and Figure 4 As shown, a further implementation method for the positioning through holes 10 is provided. Multiple positioning through holes 10 are arranged in an array on the positioning mold 1. The multiple positioning through holes 10 are arranged in a multi-horizontal and multi-vertical manner on the regular positioning mold 1, making full use of the space of the positioning mold 1.

[0047] In one embodiment, such as Figure 1As shown, a feasible structure for the positioning through hole 10 is further provided. The positioning through hole 10 includes a first through hole segment 100 and a second through hole segment 101 connected sequentially from top to bottom. That is, the first through hole segment 100 is located at the upper part of the positioning through hole 10, while the second through hole segment 101 is located at the lower part of the positioning through hole 10. The diameter of the first through hole segment 100 matches the diameter of the blood collection tube 3. The diameter of the first through hole segment 100 is larger than the diameter of the second through hole segment 101. In specific implementation, since the diameter of the blood collection tube 3 matches the diameter of the first through hole segment 100, and the diameter of the second through hole segment 101 is smaller than the diameter of the first through hole segment 100, the blood collection tube 3 will be located above the second through hole segment 101 and locked in the first through hole segment 100, so as to realize the accommodation and installation of the blood collection tube 3 in the positioning through hole 10.

[0048] In this embodiment, as Figure 1 As shown, an annular step 102 is formed between the first through hole section 100 and the second through hole section 101. The annular step 102 is used to support the blood collection tube 3. The first through hole section 100 and the second through hole section 101 are arranged coaxially. In specific implementation, part of the bottom of the blood collection tube 3 will be located inside the second through hole section 101, while the inner edge of the annular step 102 will support the blood collection tube 3.

[0049] In one specific embodiment, such as Figure 1 and Figure 2 As shown, a further implementation method of the reflector 2 is provided. The reflector 2 abuts against the positioning mold 1. The reflector 2 is bonded and fixed to the bottom of the positioning mold 1. That is, the reflector 2 is set on the side of the second through hole section 101 away from the opening of the first through hole section 100. The reflector 2 completely covers the positioning through hole 10 at the bottom of the positioning mold 1. For example, the four edges of the reflector 2 are tightly fixed to the four edges of the positioning mold 1, and the inner bottom surface of the reflector 2 abuts against the inner bottom surface of the positioning mold 1. When the laser enters the bottom of the positioning through hole 10, it will be reflected by the reflector 2.

[0050] In one embodiment, the reflector 2 is a reflective aluminum foil.

[0051] In one specific embodiment, such as Figure 1 and Figure 2 As shown, a feasible structure for the positioning mold 1 is further provided. The bottom of the positioning mold 1 is provided with a ring-shaped support leg 11. The ring-shaped support leg 11 is arranged adjacent to the peripheral edge of the positioning mold 1. The ring-shaped support leg 11 encloses and forms a light-shielding area. All positioning through holes 10 are located within the light-shielding area. A reflector 2 is provided within the light-shielding area. In specific implementation, the ring-shaped support leg 11 located around the reflector 2 can play a light-shielding role. The reflector 2 is less affected by the ambient light, so that the reflector 2 is in a dim environment, and the laser reflection effect is better.

[0052] In one embodiment, the height of the reflector 2 is less than the height of the annular support leg 11. The bottom of the reflector 2 is connected to a support plate 12, and the bottom height of the support plate 12 is flush with the bottom height of the annular support leg 11. In specific implementation, the bottom of the support plate 12 is flush with the bottom height of the annular support leg 11, which can ensure that the entire glue dispensing machine empty tube detection fixture is placed stably and can prevent light leakage from the reflector 2.

[0053] In this embodiment, the positioning mold 1 has a regular shape, such as a circle, a direction, or other polygons.

[0054] In one specific embodiment, to improve the level of automation, the empty tube detection fixture of the glue dispensing machine also includes a PLC controller (Programmable Logic Controller). The PLC controller is electrically connected to the laser sensor. The PLC controller is used to receive the signal from the laser sensor and generate empty tube information of the blood collection tube based on the signal from the laser sensor. That is, the PLC controller compares the signal from the laser sensor with the built-in preset signal to determine whether the blood collection tube 3 on the positioning through hole 10 is empty. The PLC controller has a built-in comparison module and a storage module. When a comparison is required, the comparison module compares the preset voltage signal stored in the storage module with the voltage signal of the laser sensor and outputs the corresponding high and low levels. For example, the high voltage circuit is set to the empty tube information of the blood collection tube, and the low voltage circuit is set to the blood collection tube information with blood. The current state of the blood collection tube 3 is determined on the corresponding circuit, thereby completing the judgment of whether the blood collection tube 3 is empty.

[0055] It should be noted that the circuit of the comparator module is readily known to those skilled in the art, and they can select a suitable comparator circuit as needed, which will not be elaborated upon here.

[0056] In one embodiment, the empty tube detection fixture of the glue dispensing machine also includes an alarm; the alarm is electrically connected to the PLC controller, and the alarm is used to send an alarm signal when it receives information about an empty tube in the blood collection tube. Specifically, the alarm can be an audible and visual alarm.

[0057] The second aspect of this utility model provides an adhesive application device, comprising:

[0058] The glue-adding mechanism has its glue-adding port installed on a three-axis movable mechanism. The glue-adding port of the glue-adding mechanism is used for glue-adding and sealing of blood collection tube 3.

[0059] The first aspect is the glue dispensing machine empty tube detection fixture. The controller of the glue dispensing machine empty tube detection fixture is electrically connected to the glue dispensing mechanism. The controller is used to control the glue dispensing mechanism to stop when it receives the empty tube information of the blood collection tube. That is, the controller can control the glue dispensing mechanism to start and stop according to whether the blood collection tube 3 is empty.

[0060] In the operation of this embodiment, several blood collection tubes 3 are placed in the positioning mold 1. Then, the laser sensor located above the positioning mold 1 emits a laser, which is received by the controller and detected whether the blood collection tube 3 is empty. If it is empty, the controller controls the glue-adding mechanism to stop adding glue and alarms, so as to avoid the glue-adding mechanism from adding glue to the empty tube, reduce resource waste and improve product quality.

[0061] The third aspect of this utility model provides a conveying device, comprising:

[0062] The conveyor mechanism, with its conveyor belt used to transport the positioning mold 1;

[0063] The glue-applying mechanism has its glue-applying port installed on a three-axis movable mechanism. The movement path of the glue-applying port of the glue-applying mechanism partially overlaps with the conveying path of the conveying mechanism. The glue-applying mechanism applies glue to seal the blood collection tubes 3 on the conveyor belt.

[0064] The first aspect of the glue dispensing machine empty tube detection fixture has a controller that is electrically connected to both the glue dispensing mechanism and the conveying mechanism. The controller is used to control the glue dispensing mechanism and / or the conveying mechanism to stop when it receives information about the empty tube of the blood collection tube 3. That is, it controls the start and stop of the glue dispensing mechanism and / or the conveying mechanism according to whether the blood collection tube 3 is empty.

[0065] Among them, the laser sensor of the empty tube detection fixture of the glue dispensing machine is mounted above the conveyor belt. When the photoelectric sensor of the conveying mechanism detects that the positioning mold 1 is located in the area of ​​the laser sensor, the photoelectric sensor sends a signal to the control component inside the conveying mechanism to stop the conveying, so that the laser sensor can detect the positioning mold 1.

[0066] In the operation of this embodiment, several blood collection tubes 3 are placed on the positioning mold 1, and then the positioning mold 1 is placed on the conveyor belt of the conveying mechanism and the conveying is started. When the positioning mold 1 moves to the bottom of the laser sensor, the conveyor belt stops conveying, the laser sensor emits a laser to detect empty tubes, the controller receives and detects whether the blood collection tube 3 is empty. If it is empty, the controller controls the glue application mechanism to stop glue application and alarms, and the conveying mechanism stops transporting, so as to avoid the glue application mechanism from applying glue to empty tubes and to avoid unnecessary waste caused by the conveying mechanism transporting empty tubes, thereby reducing resource waste and improving product quality.

[0067] In summary, this embodiment provides a tooling for detecting empty tubes in a glue dispensing machine, a glue dispensing device, and a conveying device, achieving the following three effects: ① Non-contact detection: The presence of test tubes can be detected without contact with the test tubes; ② Instant stop protection: The response time from detection to stopping on the track is ≤0.5 seconds; ③ Modular design: Quickly adapts to different mold specifications, with a changeover time of <2 minutes.
